(CLARK COUNTY) - A 71-year-old pilot is grounded at the Clark County Jail this week.

Indiana State Police say Allan Richer had more than 200 pounds of marijuana on board his plane when he landed at the Clark County Regional Airport. And it's what police say he did before he landed that set off alarms.

Trooper Nathan Abbott says the plane landed on Friday and his K-9 unit was brought in the next morning to search the plane. Police obtained a search warrant after the dog alerted there were narcotics aboard. The street value of the marijuana is more than $300,000.

Abbott says ISP was contacted by customs officials after Ritcher's flight plan sent up red flags. Ritcher flew out of an unknown air strip in California and was picked up on radar over Arizona, then landed in Oklahoma and declared a flight plan which he did not follow. And police say that is common tactic of drug smugglers.

Police belive Ritcher was headed east where someone is still expecting a delivery, but won't be getting it, because Ritcher is now locked up at the Clark County Jail and is being held on a $100,000 cash bond.
